HEAD TURNER

By
Garrett G. on
12/3/2014

Installed yesterday. If you thought your 2015 was a head turner already, wait until you get the Gibson installed.

From the videos online it sounded clean, not too loud, with a good note. The exhaust note IS good, but the videos do it no justice for how loud it actually is. Don't get me wrong, I love it, but it is A LOT louder than I imagined from watching the videos. They capture how smooth it sounds but none of them capture how loud it really sounds.

I asked the wife what she thought, and she said, "I guess if you like really loud cars you'd really like the way this sounds." I asked a friend how he liked it and he told me it sounded like a mustang with exhaust. There is one vid on YouTube of an owner showing off the Gibson, and a few days later there is another vid of his car with magnaflow street. He said it was TOO loud for him.

I think if you want your car to sound loud but good, Gibson is the way to go. I can't comment of performace as I havnt got on it since the install. I like it and am glad I purchased it. If it were any louder I might have had second thoughts.

Yes, I would recommend this item to a friend!

Gibson Catback Exhaust

By

12/3/2014

I ordered this kit for my 2015 Mustang GT. I previously had a Gibson axleback system for my 2010 Camaro which was great. This kit is leaps and bounds better. Great sound. Haven't dynoed the car, so I'm not sure on the power gains but I could definitely feel the difference the kit made. Did I mention the great sound.? I'd recommend the Gibson kit over anything else!

The sound is awesome. I absolutely love it! It sounds nice and throaty. The car feels like it gained a little bit of power but it could be just me leaving it in gear a little longer just to hear it. Overall I highly recommend it.

Gibson exhaust

By
Mr. Exhausted on
3/14/2015

Ok....first, I'll say the sound on this exhaust sounds great....not too load nice deep tone and the tips were really nice. However, when I tried to install it I had problems with alignment. I couldn't get the x- pipe to fit the mufflers correctly so I ended up taking it to an exhaust shop and had them install it. They also stated that the exhaust wasn't made correctly because they had to cut and weld to get it to fit properly. Does that make it a bad exhaust?? Absolutely not. I'm sure Gibson does a good quality check b4 they go out, but I think this one may have squeezed through. Would I recommend this exhaust......yes I would. Other than the fitment issues I had, it's a great exhaust. 3 starz due to fitment issues and cost me an additional $150 to get it corrected.

Yes, I would recommend this item to a friend!

Sounds Great and a Great Fit

I bought these Pipes a few weeks ago.. They are the bomb. Makes my 2015 (5.0) sound mean.. Doesn't make it sound like a Tin Can, nor is it Rasp. After Dyno Testing, My car gained 39 horses back. For the Price compared to the Ford Racing Pipes. Is UnBeatable. My partner bough the FordRacing Sport Backs, (He like mine better).. Oh Yea.

Love the Gibson 3" Stainless Catback Exhaust

By
Darrell E. Smith on
3/12/2015

I researched all of the available catback systems on the market before deciding on the Gibson exhaust. I had a Ford Racing axleback on my 2011 Mustang GT....but wanted to try something different for my 2015 GT. The power difference was immediate, and the sound was incredible. It is actually like a V8 symphony. It's too bad that my local Ford modification shop does not believe the HP gains that Gibson claims for their 3" catback. I have offered to let them dyno my car (on their nickel) to prove Gibson's claims....but so far they don't want to put their money where their mouth is :-) Maybe Gibson can give these guys a call(Pro Dyno, Ft. Mill, SC) and explain how their system makes an additional 32 hp to the rear wheels. I certainly felt it, and I have owned and modified over 20 different cars including four 911 Turbos, and four V8 Mustangs.

I've owned 3 Mustangs & have always used Flow Master exhaust but thought I would try something different on my new 2016 Mustang GT Convertible. The sound is pure muscle car & the usual drone is hardly there. The fitment was easy & I had my local muffler shop install & weld the pipes so it was one piece like the factory exhaust. The only problem is because mine was a convertible it had frame stiffeners installed & they wouldn't bolt back on because the exhaust pipe was bigger. I took it to a fabricator who modified them where they bolted onto the 3rd member & they are actually stronger now. Love the sound & performance!

HOLY COW!!!

I ordered this exhaust and it actually arrived 2 days earlier than they estimated. All I can say is WOW! This thing is LOUD!!! Under load it is really loud inside the car but once up to cruising speed not bad at all. The sound is amazing, everybody loves the way it sounds, and definitely turns heads. The fit is perfect and installation was easy. I had it installed in about an hour and a half by myself, with a jack and jack stands. My wife just had to hold the mufflers straight while I tightened everything down. If you want an amazing sound and extremely easy install I would definitely advise checking out this exhaust.

I would have given this system 5 stars had it not been for the terrible packaging it came in, no padding of any kind. It was just a big cardboard box with everything tumbling around inside, fortunately they did bubble wrap the tips so they weren't dinged up, but everything else was. This exhaust is loud, but not obnoxious. I think it sounds better than several of the other big names that are available. If you want people to know you're there, this is the one for you. LMR- the packaging cost you a 5 star rating.

Sounds good but...

By

Sounds good...much louder than stock cat back BUT it does not deliver the advertised gain in HP...website claims a 32hp gain and I only gained 5 RWHP and 5 RWTQ after install. Dyno'd the same day with the same conditions.

Also, the box it comes in was not packaged very well and as a result my exhaust had a few dings in it.

Sounds Fantastic

Installed this system about a month ago on my 2015 GT. Installation was fairly simple, just make sure you have someone to help. I did mine in my garage with jack stands. After installation I started it up and was amazed at the difference. The sound is deep and loud but not raspy like was nervous about. It's toned down just slightly since it has broken in, but still sounds fantastic. You can't beat the price for a quality name like Gibson.

good fit, easy install, but very loud inside

By
Stephen B. on
8/2/2017

I bought these a couple of months ago based on reviews from others about being moderately loud and having little drone inside, they must be deaf. I have a 30% hearing loss and tinnitus and these are way too loud inside the car for me. The x-pipe is cut and welded together between the two pipe right under the passenger compartment and the drone is almost unbearable at highway cruising speeds. I purchased a hooker blackheart for my wife's 2014 GT CS and her x-pipe is a stamped stainless chamber that results in nearly NO drone, but a good sound out the back of the tail pipes. My wife tells me she can hear me coming home almost a mile away. So if you want loud, all the way around (not as loud as open pipes) then this is the system for you, but is you want to travel on long trips and be able to still have some hearing left at the end, then these are not the exhaust for you. Performance wise, there was a slight increase in power output. Just remember you have to reuse the cat clamps up front, there is a tab that you need to put a screw driver under and pry up on to pull the pipes off after you loosen the clamp bolts. If you damage these, you will be spending over $60 each for the clamps from a ford dealer or on line. I hope this helps you make an informed decision. If I could find someone wanting this system, I would be happy to talk a trade so I could install something less loud in the interior.

Great Race Car Sound

By

6/3/2016

I bought this over the MagnaFlow based on video sound and price. Installed myself and took about an hour with little difficulty. I appreciate the LMR instruction video! Would've given 5 stars however the product quality didn't deserve it. The box came ripped open and the black paint was chipped on the exhaust tips. Very disappointed in that cause I'm not returning it and waiting forever for a replacement when I have Camaro doors to blow off! Sound is louder than expected but does sound very good. The sound is loud at 3000 rpm and racy for the next 3,500 to redline. I try to keep rpms around 3 or less in town as it sounds like "Godzilla gargling chainsaws"! Definitely turns heads and makes other rice burners try and race me.

By

The only complain I have is the packaging it came in, the box was torn open in sections and not very tightly packed at all. The muffler and tips were wrapped sufficiently that no damage was done fortunately. The x-pipe and clamps were not harmed. The instructions state you need to disconnect your battery for installation but this is not necessary at all.. The computer will learn the exhaust within 10-15 miles of driving. As far as the power gains, it does feel a little more responsive. I haven't added a tune along with it and my K&N filter yet but I'm sure it will wake it up even more!

Louder than expected

By
Paul R. on
7/4/2016

First things first....I like it. With that said, it is much louder than I expected based on other peoples reviews. First through third gear definatley have a drone to it, but you learn where to shift early or later to minimize the drone sound. Freeway speeds are fine, as long as you aren't under load (going up a hill or whatever) the car is quite. Now, when you want to get on it and have some fun, the car sounds great. Start up sounds like a V-8 should sound throaty. Hopefully I'll get a video up on you tube comparing the before and after sounds.

Good Fit

I bought this system a week ago & had it installed by my local muffler shop. The old system came off as advertised in one piece & the new one went on with ease. The one problem is I ordered my 2016 Mustang GT Convertible with the performance package and it had rear frame stiffners installed that had to be removed to get to the exhaust & would not go back on because of the bigger exhaust pipes. Will have to visit another mechanic to see if he can modify them to reinstall. Other than that it has a great sound & a kick in the seat response.

I have had 3 Mustangs & always used Flow Masters but decided on Gibson this time and love the sound. Also no drone when under a load just "music" to the ears when you hit the accelerator. The 2016 Mustang convertibles have frame stiffeners & because the exhaust pipes went from 2 1/2 " to 3 " they wouldn't go back on so I'm having my local speed job fabricate a bracket to reinstall them.

I would dof payed more for this system. Ive had it on my 15 for a month now. And it gets complements everywhere. My buddy purchased the ford racing borla system for his15 and everyone seems to like mine better. Dont pay double for the top brands when you dont need to. Your just paying for the name stamped on the muffler that you cant even see when installed. Awesome exhaust!
